How to create a Vector of Numbers from 1 to N in C++

How to create a Vector of Numbers from 1 to N in C++ ?

Answer

To create a vector of numbers from 1 to N in C++, you can use a loop to generate the numbers and push them into a vector.

✐ Examples

1 Create Vector of Numbers from 1 to N

In this example,

We include the header to use the std::vector class and the header to use input/output streams.
We define a function named generateNumbers that takes an argument n of type int, which represents the end value.
Inside the function, we create an empty vector named numberVector of type std::vector.
We use a for loop with an iterator i ranging from 1 to n (inclusive).
Within the loop, we push each value of i into the numberVector vector using the push_back method.
We return the numberVector vector containing the generated sequence of numbers.

C++ Program

#include <vector>
#include <iostream>

std::vector<int> generateNumbers(int n) {
    std::vector<int> numberVector;
    for (int i = 1; i <= n; ++i) {
        numberVector.push_back(i);
    }
    return numberVector;
}

int main() {
    int n = 10;
    std::vector<int> numbers = generateNumbers(n);
    std::cout << "Numbers from 1 to " << n << ": ";
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

Numbers from 1 to 10: 1 2 3 4 5 6 7 8 9 10

2 Create Vector of Numbers from 1 to 100

In this example,

We include the header to use the std::vector class and the header to use input/output streams.
We define a function named generateNumbers that takes an argument n of type int, which represents the end value.
Inside the function, we create an empty vector named numberVector of type std::vector.
We use a for loop with an iterator i ranging from 1 to n (inclusive).
Within the loop, we push each value of i into the numberVector vector using the push_back method.
We return the numberVector vector containing the generated sequence of numbers.

C++ Program

#include <vector>
#include <iostream>

std::vector<int> generateNumbers(int n) {
    std::vector<int> numberVector;
    for (int i = 1; i <= n; ++i) {
        numberVector.push_back(i);
    }
    return numberVector;
}

int main() {
    int n = 100;
    std::vector<int> numbers = generateNumbers(n);
    std::cout << "Numbers from 1 to " << n << ": ";
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

Numbers from 1 to 100: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
